May 2011 Bottom Sediment Class Polygons Covering the Oceanic Nearshore of Assateague Island from Ocean City Inlet to Toms Cove Hook

Bottom sediment class polygons based on acoustic seabed classification data developed from side scan sonar data. These polygons were created as part of a study, funded by the National Park Service, to create a baseline inventory of submerged marine resources within and immediately adjacent to the Assateague Island National Seashore boundary. The study area included the Atlantic nearshore area extending out to approximately 1.5 km offshore, along the 58-km Assateague Island shoreline. In addition to the side scan sonar data, other geophysical data including bathymetry, sub-bottom seismic profiles, sediment, and underwater video imagery, were used to further delineate the bottom class polygons.
